Well, you aint gonna get 52 volts exactly. Not with 18650's. But you can get 54-55 volts. Why you stuck on 52?
Spot welder is the way to go. I have one if you ever find yourself in LA, Im happy to let you use it. Otherwise, you can buy a decent one on Amazon or Ebay or like $175.00.
You can also just take a typical m365 pack or similar and solder long wires to it and then make a separate 3s3p pack and connect it in series. Thats what I usually do and it works great. You can charge them separately...the m365 pack with the regular bird charger and the 3s3p pack with a 12 volt car charger and then hook em back together when youre done. That way you wont need to buy a separate charger (provided you own a car battery charger). Another advantage is that you can put the add on pack in a remote location giving you more design/space options. Ive been doing this with my scooter builds. It works very well.
And lastly, I have a 54 volt battery pack off of an old e-bike. Ready to go. PM me if you want it.
Take care homes.
Oh, Hows that ice chest scooter project going anyways? Im working on one a lot like it. Totally stole your idea, but it was just too cool to pass up. An ice chest you can RIDE? Love it.
